Friction and Wear 4 Ball EP and Wear testers

Four Ball EP and Wear testers

  Micro Processor Controlled System For Data Acquisition & Real Time Analysis:

Four Ball Machines used for testing extreme pressure &  wear Preventive characteristics of lubricating oils, greases, evaluation of cutting fluids and polymer containing oils. Imperial Four-Ball Machines designed to perform tests as per the following International Standards ASTM D2596, ASTM D2783, ASTM D2266, ASTM D4172 , FTMS 791-6503, IP 239, GOST 9490-77, DIN 51834-1&2  Comprises of:

  • 2 HP variable speed drive Pneumatic loading system
    (manual/ programmed) load cells for Friction Force and load measurements Digital display for temperature, speed time, load and friction force
    Load Pneumatically activated, continuous loading max range 1000 kg.
    Speed Variable speed drive, continuously variable 2HP/220 V Max. range 60-3000 rpm (specify voltage while ordering)
    Temperature Thermostatically controlled temperature of specimen holed range ambient to 250°C.
